Specification of Letters Patent.

Patented Feb. 23, 1915.

Application filed July 22, 1914. Serial No. 852,500.

Be it knownthat I, JOSEPH N. SUPRU- NowsKI, a citizenofthe UnitedStates, residing at Toledo, in the county of Lucas and State of Ohio,have invented new and useful Improvements in Car Attachments, of whichthe following is a specification.

This invention relates to improvements in the air line equipment ofcars.

The leading feature of .my invention consists in providing a meanscombining the cut-off valve feature and dust collecting feature whichconcerns the air line mechanism with which railway cars are equipped.

"The general practice invogue todayfis uch" the air pump engine, and forcollectingthe dust that may accompany the airthrough' the various airpipes with which the car is provided. 7

-One.of the important objects of'my invention consists in providing asimple, inexpensive, and highly efiicient combined cutolf valve and dustcollector for air line systems of cars which is characterized bysimplicity of construction whereby the expense of providing more thanone connection for the accomplishment of these functions is obviated andwhereby the hazard of freez ing the dust collecting apparatus which istoday felt is overcome.

A further obJect of my invention lies inthe provision of a singlecasting so con structed' that the air which is forced through the airpipe of the car is utilized for the purposenof discharging the dust,moisture, and all"'foreign particles with which the air may beladen'from the pipe line and at, the same time to provide for drainingthe casting of any such accumulations of foreign particles. Y

The present practice of removing the dust from air pipes consists inremoving screw plugs from one or more points along the length of thepipe and this operation is only done when the car shall have beenremoved on a repair track andthisrequires considerable time andexpenseto assure that v the air pipes are in good order and workingcondition. It has been found that the moisture present in the air pipeseven if col- 'lected in the present types of union and similar pipeconnections results in the freezing" device and cut-off valve in an airline system and to locate a single connection 'at a polnt where the samemay be more readily accessible for the purpose pf inspection and repairsthan has hitherto been found to be thebase as well as to e'lficientlyprovide for discharging the dust and draining the moisture that may bepresent. in the air pipes of said system.

With the above andother objects in view my invention consists in thecombination, arrangement, and details of construction disclosed in thespecification and accompanyingdrawings, and then more particu larly'pOmted-out in the appended claims.

In the drawings, wherein similar reference characters designate similarparts throughout the respective views, Figure l is a side elevation ofmy invention showing it mounted in proper position upon an air line ofpipe. my invention, Fig. 3. is a detailed View of a deflector to bedescribed, Fig. 4 is a sectional view of-a cleaning valve andaccessories to be described, Fig. 5. is a sectional view of a modifiedform of my invention, and "F ig. 6 is asectional view of the defiectormechanism of my modified invention.

Referring to' the drawings which. are

.the inlet pipe 2, the plug being provided with a port 7 with which isadapted to register the port 8 formed in the plug seat 6. The internalconfiguration of the union will be irregular so that metal will bemassed at such points as will be effective to provide a passage 9leading immediately from the 'inlet pipe 2, an admission passage 10 of adiameter less than one-half the diameter of the inlet or outlet portleading downwardly from the passage 9 and an upwardly extendingdischarging passage 11 a diameter Fig. 2 1s a sectional view-of inletor'outlet port communicating with the outlet pipe 3. By thisconstruction it-will.

be seen that a circuitous course and passage 5 is proyided for theair'in passing from the inlet into the outlet pipes.

12 denotes a suitable deflector which in this instance is shown in theform of a concavo-convex hood the same being sustained in positiondirectly underneath the passage 10 by such means as upright stems 13,the latter being provided so as to provide clearance spaces for thepassage of the collectings deposited by the air passing 1 through thesaid passages out of the outlet pipe 2. Aspecial mounting and connectionis pro videidizwhich is adapted to be removably secured'to the pipeunion 1 and which carries or inay carry the deflector 12. This mountingis virtually a valve casing 15 having a threaded nipple 14 threaded intothe pipe union and this, valve casing has a bore 16 extending from endto end thereof. Formed to receive the conical plug 18. It will be seenthat the conical valve seat '17 corn-v miinicates with an annularchamber 17. The conical plug 18 is provided with a spring socket 19 intowhich projects one end of a coiled spring 20 the opposite end beingsnugly received in the spring cap 21 I which is threaded into theannular chamber 17', a nut 22'being integrally formed upon said capwhereby the samefmay be readily removed. The spring 20, it will beunderstood, will beput underitension so as to cause the conical plug 18to lie' snugly in its seat. The plug 18 is provided with a transverseopening 23 which, when the plug shall have been rotated a satisfactorydistance, will register with the bore 16 formed in the valve casing 15.An operating handle- 5 24: serves to rotate the valve plug to bring itsport or opening into registration with the bore 16 so as to provide aclear passage for the escape of dustand drainage. 24' denotes a nippleformed upon any part of the air pipe line and the outlet pipe 3 ofapplicants union 1 will bethreaded v upon said nipple therebyestablishing intercommunication between the union and said airline atonev point and by means of suitable pipe connections engaging the inletend of the union 1 which latter will be properly mounted position. It iscontemplated that the\union 1 should be so located as to make it easyfor the same to beinspected and cleaned if desired.

Rust scale and dirt collects in the dust collector which applicantprovides and which is formed at the lower end of the union in the spacesurrounding the stems of 5 the deflector, and through the use of theplug or valve 18 it will be possible for any in the casing 15 is aconical seat 17 adapted portant featurev of draining the air line cannotbe overlooked as water accumulates from moisture in the air pumpedintothe train line and then collects in the bottom of the dust collector.and would ordinarily freeze causing the pipes to burstthereby causing agrea-tamount of delay to the cars in transit. By means of applic'antsvalve 18 the bottom of the dust collector can'be opened at any time sothat'no dust can accumulate which cannot be readily expelled. By-opening this valve the car charged with air will serve the usefulpurpose of enabling this air to expel the foreign particles. -The airentering through the inlet pipe, 2 will pass downwardly through theadmission passage 10 when itsv path will be broken thereby affordingv anopportunity for any dust or moisture to-settle upon the deflector whencethe same will be diverted into the dust collector and will remain thereas long as the port or opening 23 formed in the conical In 18 is out ofregistration with the bore 16 formed in the valve casing 15. The airbeing thus rid of its foreign particles andhaving its course divertedwill pass upoutlet pipe 3 to continue its flow to the point wheredesired. Of course the handle 5 con-' trolling the operation of plug tmay be manipulated to cut off thesupply of air as may be desired. Whenthe opening 23 is in registration with the bore 16 and air is'passingthrough the union l the same will expel the dust or moisture through thebore 16 so vwardly through the passage 11 out of the hitherto describedexcept as concerns the 1 construction of the drain valve which will nowbeset, forth. The deflector 25 is ofthe same shape as the deflector 12already described and it is supported upon a stem -26 which is connectedto a plug 27 arranged to close a plug seat 28 formed upon a tube 29removably connected to the union and 30 -is a spider supported in saidtube 29 through which passes the rod or stem 26. A spring 31 is coiledaround the rod 26 and bears at oneend against the spider and rests atits opposite end upon the oppositely disposed levers 32 which aresuitably fulcrumed upon pivots 33 provided in the clearing spaces in thetube 29, said levers being disposed obliq'uely with respect to said stemand being operated by means of such flexible elements as cords 34. Thecords 3 L will lead to any desirable point along the air line and whensaidcords are pulled the levers will be forced upwardly thereby puttingthe H spring- 31 under'tension 'unseatin-g theplug which is free to movewith the stem 26 thereby enabling the air under pressure to expel thedirt or moisture from the union out of the bore 35 formed in the tube29.

ditions where it is desired to actuate the valve controlling thedischarge of the dust from some distant point.

Numerous modifications may be resortedv to in practice without departingin principle from the details of construction herein disclosed.-

What I desire to claim and secure by Letters Patent is l. A dust andwater trap for fluid pressure lines, comprising a T-shaped couplinghaving formed therein an air inlet port, an air outlet port, and acircuitous passage of a diameter less than one-half of said-inlet andoutlet ports connecting said inlet and outlet ports and having itsintermediate portions enlarged to form an expansion chamber, aconcavo-convex deflector in said chamber, and means journaled in thewalls of said coupling for establishing communication between saidexpansion chamber and i the atmosphere.

2. A dust and water. trap. for fluid pressure lines comprising aT-shaped coupling having formed therein an air inlet port, an air outletport, an expansion chamber, an air admission passage establishingcommunication between said air inlet port, and said chamber, and adischarge passage establishmgcommunication between said outlet port andsaid chamber, a deflector having a convex upper surface in said chamber,the access of said admission and discharge passages intersecting at theupper surface of said deflector, and means ournaled in the walls ofsaidcoupling for establishingcommu'nication between said expansionchamber and the atmosphere, said means comprising a plug rigidlyconnected to said deflector, a casing threaded into said coupling, saidcasing having a valve seat to receive said plug,

a coil spring for seating said plug and levers swingingly mounted onsaid casing and pivotally connected to said plug whereby the lattercan'be unseated against the tension of said spring.
